From the Super Mario Wiki
The Pink Mushmellow is a kart that appears in Mario Kart Tour. It is a magenta variant of the Mushmellow, specifically one that uses Toadette's color scheme, and is classified as a tour-exclusive Normal kart. Boosting from Dash Panels lasts longer and yields more points when using this kart. The Pink Mushmellow was available in the Paris Tour, where it was part of a Tour Gift for Gold Pass members after getting 84 Grand Stars. The kart's tires resemble the Mushroom tires from Mario Kart 7, although pink-toned and with a different shape.
